Ammonium Chloride → 1-Acridinol, 1,2,3,4-tetrahydro-9-(((3-fluorophenyl)methyl)amino)-

Participants

Reaction Steps

In 100 ml of THF was dissolved 300 g of 3,4-dihydro-9-(3-fluorobenzylamino)acridin-1(2H)-one. The mechanically stirred solution was cooled in ice under nitrogen and 4.68 ml of 1M lithium aluminum hidride in THF was added dropwise over 15 minutes. After 0.5 hours, analysis by TLC indicated the reaction was complete, so it was neutralized with 1 ml of saturated ammonium chloride solution and the resulting salts were filtered. The filtrate was evaported to an oil which crystallized on trituration with pentane. The solid was filtered and recrystallized from 1:1 dichloromethane/pentane to yield 2.50 g of solid, mp 128° C.
